New U.S. Food Guidelines Stress Vegetables, Grains

The Federal government's new dietary guidelines are out and they're being hailed as the strongest yet.

The guidelines, updated every five years, recommend eating up to 13 servings of fruits and vegetables a day and specify that at least three of the daily servings of grains be whole grains such as whole wheat, oats or brown rice.

They also emphasize getting at least 30 minutes of exercise every day — an hour for children. And officials said the "food pyramid" may be replaced by something easier to understand.
